For three 150mm² cables in RSC (Rigid Steel Conduit) pipe, the ground cable size should typically be determined based on the total current-carrying capacity and local electrical codes. Generally, a ground cable size of 35mm² to 50mm² copper is often recommended for such installations. However, it's essential to consult the relevant standards and regulations, as well as consider factors such as conduit fill and installation conditions, to ensure compliance and safety.

What is the difference between armored cable and flexible metallic conduit?
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
What is an earth cable?
ive only been on an electrical installations course for 2 days, but basically the earth cable does nothing.its a safety feature, so that any fault which happens in a wired system, will be taken by this cable straight to the ground, instead of to you, so this earth cable needs to be completely fit, and properly fit to every electrical component.

Can schedule 40 plastic pipe be used above ground with naural gas?
ASTM D1785 does NOT approve that pipe for use with natural gas - PVC schedule 40 / 80 / 120 is approved for use of pressurized liquids ONLY. The ONLY plastic (type) pipe approved for Natural Gas above ground is "Polyethyline" pipe "PolyPipe" that uses special heat sealed fittings. (ANSI 58 / ASTM D2513)

What precautions should be taken in laying power cables in an underground trench?
Before digging the trench, make sure there are no lines or cables under that ground. In rural areas there should be no problems. However, in urban areas it would be advisable to call MISS DIG. Be sure that the cable is in some kind of water-tight conduit or pipe, dug to proper depth, and clean sand or pea stone is placed around the pipe to protect it.
Where is the crankshaft position sensor located on a 2006 Chrysler Town and Country?
With a 3.8l engine, remove the battery and the tray it sits on. I also removed the cable connected right behind the trans dipstick as it gave me more room to work. The cable here goes to a group of cables below. Part of that group of cables is the sensor cable, should be easy to find when you follow the cables as they go toward the passenger side and the rear. To give you more direction, between the trans dip stick and the engine is an exhaust pipe that crosses to the back. The sensor is below this pipe. I believe it uses a 10mm socket to remove the bolt.

Can triplex be buried in ground in pipe?
Yes, triplex cables can be buried in the ground within a conduit or pipe, provided they are rated for direct burial or installed according to local electrical codes. Using a conduit protects the cables from moisture, physical damage, and environmental factors. It's essential to ensure that the conduit is properly sealed and that the installation adheres to safety regulations and standards. Always consult with a qualified electrician or local code authority before proceeding.

If it has a metal body you attach a suitable cable to match the ground or earth wire colour in your country ( such as a 6 mm squared cross sectional area ) copper cable with green-yellow ( in the U.K.) insulation colours to the metallic frame of the dishwasher with a cable lug and a brass ( preferably ) nut & bolt. Then using a suitable length of cable to the nearest grounded piece of metalwork such as a copper pipe using a "earth clip" for a copper pipe. These can be bought from electrical wholesalers who supply all electricians or / and electrical contractors.
